City College Slaying Case

On Friday, police released its new efforts to track down Perez with Spanish-language flyers.

Janette said she was glad the police were reaching out to people in Mexico to try and find the alleged killer. A $1,000 reward has been offered, and a Mexican telephone line has been installed to receive tips.

"We're, in a way, happy because now we know it's going to go more out there in Mexico," said Janette Gonzalez, sister of Diana. "Hopefully, we can get more results out of it."

The victim filed a retraining order against her estranged husband just weeks before her murder. She told police that Perez had kidnapped her for three days in Sept. 2010. Court documents said he sexually assaulted her, but no charges were filed. Experts believe evidence was not strong enough to prosecute.

The Gonzalez family hopes the recent efforts will lead to Perez's capture.

"Nothing that they do right now, even if he goes to jail, nothing's going to bring my sister back," Janette Gonzalez said. "But we want to see him in jail. We want to see justice for it."

While police believe Perez in hiding in Mexico, the Gonzalez family lives uneasily knowing the potentially violent suspect could return at any time.

"My brothers, me myself, my husband, we're always [thinking] like that because we don't know," Gonzalez said. "We live here. He knows where we live, so you never know."
